The only video on UA-cam as of now which is showing Spo2 accuracy for Series 6. Thanks, that's what I was looking for.👍
But this was totally useless video, since there wasn’t a test in low oxygen environment, in which the accuracy actually means something.
Sami Anttila maybe can try it a person with astma? Would love to see that coz im asthmatic aswell
@@hafizh4942 I’m pretty sure there’s some videos coming in aviation channels where they will test that in altitude with and without supplemental oxygen.
@@hafizh4942 ittl do the same, just your personal obs.
In the 2 attempts that failed you did move your arm a bit at the very beginning of the reading. I think Apple is prioritising accuracy as they always and should always do. Garmin for example configured their watches to allow for much more movement and as a consequence their Sop2 readings turned into random number generators.
Haha! Good point!
even if its accurate, after watching 10 videos here, everyone get 95-100, which seems like a useless number, and if you sick, its enough to get bad result once. Bottom line - just a toy, sorry red color toy ( also blue!)
Ran T Because it’s always between 95 and 100, if not you’re in trouble. Most reviewers are healthy, everything is logical.
@@albert3316 if you measure a problem that is so rare to have, then there is no need to make such a big deal out of it, especially if its not that accurate inside the 5% window, a 1% error inside a 5% window is around 20% noise. and you can't do it during sleep or workout. Bottom line its really nothing. It just works on childish Apple enthusiastics.
@@rantg Uh... Blood oxygen checks while sleeping, don't spread false info
Eric, long comment ahead, sorry 😄.. As a person that works in the medical field, my opinion is everyone knowing their saturation is great, IN A PERFECT SETTING. With the finger probe, saturation is measured by shining that light thru the finger where it is picked up on the other side by a sensor/diode..the amount of light collected gives a saturation. For the saturation to pick up on a watch, the light from the watch must be reflected off something (normally bone) to be picked up by the sensor (at least that is how it works in the hospital), so wearing the watch correctly when taking a reading is important...on top of that, many factors go into an accurate reading. For example, low hemoglobin g levels cause abnormally high saturations. Bad perfusion or cold extremities cause abnormally low readings, if a reading can be obtained at all. What I'm getting at is, as this technology has trickled down to the masses now, and I'm concerned that that the public does not get the proper instructions, training, or understanding of the techonlogy which could result in "panic" when that data is misinterpreted or just flat out wrong...
Good points, and it seems like Apple is attempting to force the user to take a good reading, otherwise it spits back an error message. Or maybe I’m just optimistic? In any regard, really appreciate your thoughts considering you are in the medical field!
I can feel that. At one point I was getting random heart rate spikes and it freaked me out. Got a lot of tests done and nothing was wrong. Lol
Some suggest to use the Apple Watch on your finger to get accurate oxygen readings but for me, using it on my finger I get completely wrong readings, sometimes so wrong that when taken seriously, I should call a doctor immediately. Therefore, if someone has a situation where he/she is in danger of having low oxygen saturation and therefore needs a regular reading, get a medical grade device and don't count on a smartwatch
So if my hemoglobin level was a 13.4 I'd be getting inaccurate readings? Now im worried 😥😫
@@tomrao4 well 13.4 is just .1 low, that won't make a difference and is not an issue, when I spoke of low levels, I meant stuff like anything less than 10g
It seems like your first two readings failed because you were putting the medical grade sensor into your finger on your other hand. However, the third time was the charm because you did not move your hand at all during the entirety of the 15 seconds.
Lol he says two failed readings but both times he moved his hand for the first 5 seconds! 🤦🏽♂️🤦🏽♂️
Definitely want to sit still when getting that reading. I know it’s been said 100 times. But we need to keep in mind this isn’t faulty tech, it’s precise tech.
I’ve never had a failed O2 reading so far.... although I’ve only had it for 24 hours! I wear it about 2/3” up from my wrist joint, and it’s not loose and not too tight.
Thanks for the vid! I love my iWatch 6! So nice to monitor this stuff on the regular.
I have seen a couple UA-camr's presentations of the sensor in action and it appears that the feature works more reliably in you tighten the wrist strap. Makes sense if you think about it. Those dedicated blood oxygen sensors really clamp down on your finger with their spring mechanisms. The Apple sensor seems to need a similar amount of clamping on your wrist to function well. It will also be interesting to see if the Apple Watch "learns" to take more reliable readings over time as it gathers more and more historical oxygen saturation data about the user. Nice video. Thanks!
Yes, it was hard for me to know if it was too tight or too loose, in general I wear the watch pretty snug. I do think that overtime that Apple will be able to calibrate the sensor to be more accurate depending on the user, but that’s just a hopeful guess. I’m interested to see how the sensor works overnight while sleeping.
Thanks for that. Thanks to this video I know that it’s not quite there yet. I’ll go for the SE for now :) not worth an upgrade. Great video
Please do a review for Casio sensors, (barometer/thermometer) are they accurate or not
Oh nice review, I prefer to buy a sensor and go for the Apple Watch SE
I think I an excellent idea for the new feature on the new Apple Watch but not enough for me to upgrade as I’ve got the series 5
Nice fenders in the back!
I have the same band, whenever I use it, the blood oxygen has trouble reading it. With the silicone one though it lets it do it consistently
If you tighten your strap a bit it reads consistently. Mine is a bit snug but it always reads without issue.
i still have the Apple Watch series 3 but i was thinking of updating my Apple Watch too the new Apple Watch series 6 in the new Blue Color
Is vivoactive 4 spo2 sensor accurate? Could you please test it
Yeah, too much movement. Same with Garmin, when they say keep still, they really mean it.
Can U review Fitbit charge 4. Heart rate at gym plss 👌🏼👌 Ur reviews are great!!
Could you please try to hold the apple watch on your finger too to test whether it measures correctly?
Thanks for this, really usefull
How it compare with a Garmin Venu or Vivoactive ?
Great comparison video. In my opinion smartwatches are a guide, but when in doubt visit your doctor.
The sensitivity could be due to Apple making the reading only while it is stationary. I am trying to determine if that is true. It may be possible that apple uses the accelerometer to make it so finicky. Why they would do that dunno. Would you consider trying an experiment to see if the watch would read the O2 level if your arm were still and motionless at your side as if just standing upright? Thank you for this video. I think Apple should enable the O2 sensor to read in real time over extended periods of time. Please let me know if your able to read your O2 while the arm is in another position. Thank you again!
What does this test tell me anyway? I don’t care about these numbers but if it benefits in some way for workout statistics this would be great.
The vo2 statistic in the health app which is calculated with your heart rate and workout data is very interesting! Saw a very linear and consistent improvement there over the year, wouldn’t even know that without that. I don’t remember how good I was a year ago.
And this helped me decide finally, ordered SE 😃
kinda silly, there are more features that matter more on the S6
Josh Hello mate...finally got S6 but honestly dunno what’s the real big deal apart from the blue colour and ecg 😀still think SE would’ve been ok
How will you know what the reading of oxygen level in hand if you hold couple of seconds breath 😁
I can’t get mine to work, it says open my watch app but nothing happens
How is the blood pressure monitor now in the series 6? I heard the past versions weren’t very accurate. Thanks for the video.
The Apple Watch doesn’t measure blood pressure.
It tracks pulse, it will do an EKG, and now blood oxygen levels.
webster695 ok thanks for the clarification. I appreciate that.
Is it better to walk faster or longer?
You need to be completely still for the series 6 to pick up on your oxygen levels. You moved a lil bit at the start of the timer
I just did a side by side with the series 6 and a dedicated spo2 device and I had my arm stretched flat on a table for the Apple Watch and the spo2 sensor on my finger and guess what, they both got the same results.
I’d really like to know if the HR sensor is better or worse than the series 4/5 configuration. I remember you found that Sensor to be leaps ahead of the series 3. But the LED/sensor config on the series 6 looks like a step back reducing the amount of sensors to make way for the blood oxygen sensors. It will really suck if the trade off is worse hr sensing for adding blood oxygen level sensing.
It should be fine for cardio, but I’ll find out what it does for a gym work out, because that could potentially be impacted negatively
Techy Agent thanks! Gym workouts was what I was thinking about. If the watch performs worse I may actually go for the SE as that is a real value add for me, I have the s2 and I always feel like gym workouts just aren’t measuring properly. (Which I understand is a limitation of the technology).
I actually thought of that 2 so I used my old apple watch series 4 which only has 1 sensor in the center like the 5 on my right wrist and the 6 on my left and put them at the same time and they gave the exact heart rate so thank god
wonder if there's a test after exercise, high elevation
These Oximeters are a well 50 and under dollaroose well spent, Get one !
Did a whole nighter and lots of data there.glad i bought one .
I did the exact same experiment and the watch was mostly 3-4% off (lower) when it would come up with a measurement, compared to the medical grade device. Once out of 10 it was only 2% off and once it was 6% off. To me that is useless. Hope a SW upgrade can improve it but I do not really believe it.
Good idea for a video Eric! Can you test the advertised 25% AOD brightness increase? I would imagine you could sit outdoors and compare the 5 and the 6 without tilting your wrist. Maybe I have found a career as a YT director. 😂.
Yeah, I’ll probably do some sort of test regarding screen brightness. I’m trying to figure out if there is some sort of scientific way I can actually do that. I may be able to take a picture of both watches side-by-side and then use a scope in my photo editing software to measure the screens in some way. On an anecdotal level, I did compare the screen of the series 6 against the series 5, and there is a very slight difference. The 6 is just ever so slightly brighter, but it’s almost imperceptible.
@@TechyAgent Nice. Look forward to it!
What about the v02 Max or whatever. How do we check that? Thanks
Every apple watch has that already. Just needs workout data and heart rate. You find it in health app. Very interesting to see. But yeah I wonder if that new sensor improves or adds some statistics.
Can you test that spo2 censer agenst the Garmin Vivoactive 4 and the Garmin instinct curious on how accurate those watches are???
I don’t currently have the Garmin instinct, however I do have a buddy who has a current generation Garmin Vivoactive, so I’ll take a look.
@@TechyAgent can you make a little video out of that too???
i meant the Garmin instinct Solar that has the spo2 censer sorry about that its the solar edition not the original.....
Timothy Pettit All the Garmins generally off about %4-5. I used to have FR 245 and VA 4. But ı dunno hpw accurate is the latest spo2 sensor on brand new fenix 6 and instinct solar models. I think Huawei has the most accurate spo2 sensor.
Anyway I am debating on which model to get Se vs the 6 .
Anyway placement of pulse oximeter do matters and that part of the wrist is not optimal . Fingertips are the standard for adult / children in the medical field, earlobe for babies. If the sensor is too sensitive on the phone doesn’t work all the time then it’s not very useful. Your pulse was high at rest though .
Thanks
Great video. It seems finicky as you mentioned, but it's nice to see that it's fairly accurate. I returned a Fitbit Sense because of how badly the Sp02 feature works. First of all, it only works during the night while sleeping, and you can't measure Sp02 at any other time. Plus, it doesn't give an accurate reading. Mahalo!
I have the fitbit versa 3 now with the SP02 feature. Did you end up getting the Apple Watch? How do you like it in comparison to fitbit? Considering returning but the Apple Watch i want is $200+ more :/
Thanks 👍🏾👍🏾
Thanks, I think I’ll skip this one and get the prior models.
Du you moved your arm during first and second measurement.
I have hairy arms. Not sure if I trust the 02 sensor to work for me.
I got my series 6 today
I have to make it tight to get a reading
I'd be interested in the developers opinion on the issue of failing measurements. I'm really not sure if "movement" or "shake" is the enemy here... As long as you have permanent contact with the skin, I'd presume that neither the sensor nor the algorithm would care for shaking. It's the same with the medical grade device. It's fastened tight, and that pretty much seals the deal.
It seems like not worth for upgrade from series 5.
As a pilot I was super excited to see this feature added however now after seeing this I’m not thrilled because needless to say not everything is smooth in the cockpit when flying. Thanks ! Do you think a software update can address this?
I’m hoping that some sort of firmware update can calibrate the sensor to be more accurate and less temperamental. I’ve continued to test it and it seems like it needs to be a little tighter against my wrist (than I’m normally used to wearing) in order to get consistent readings.
Christian Maciel That’s very kind., thank you. Editing videos I think is harder than flying airplanes!
It’s still a good buy. Like techy agent stated, as long as the watch is tight on your wrist and you’re able to keep your wrist stable (little movements shouldn’t affect it too much) you should be fine.
I tested it while driving and had no issues
Apple has stated that it isn’t a medical device it only helps for some understanding for people that somewhat don’t know anything about their system at all. Therefore it might help in more understanding what is happening in Your system, anything between 90-100 isn’t bad...where if You would continuously measure lower 90 or even 80‘s You might consider asking for a medical checkup.
Been using Garmin Fenix for about 8 years (hobby is besides sport is anatomy and physics from the human body) and some data still is interesting to read.
i think you have an issue with your watch ? it read 100% of the time , even if i move my arms, wrist ... weird
I was hoping it could work continuously like during a workout. I think I will probably pass on this watch. Maybe the next version will be able to do this.
Supposedly it will also be able to detect blood glucose sugar levels . I have the 4 it would be amazing if the 7 can actually do sugar levels I’m hoping the rumors are true
Priscilla’s Galaxy and universe That would be pretty cool. I was going to buy this one until ai learned that the o2 sensor didn’t work continuously. Not interested in this one
Pls Scanwatch
If you compare 2 medical grade units they will vary. Also if you wear artificial nails or polish those finger units can be inaccurate. Thus the watch will be better...if it works. The most accurate is arterial blood gas test. This is not practical.
Agreed plus I find more often than not you get two totally different readings from each hand with the medical spo2 monitors. I bet if he had taken both readings from the same hand it would have been even closer in the readings on both devices
They say the best way to do it is putting your watch on your finger. Obviously, they didn’t say this officially but it works apparently.
Your palm must be open and flat. If you read the error message it says to lay your hand flat against your lap or table. Making a fist makes it difficult
position the watch to the underside of the wrist, more blood there. But I still hate the apple watch
Probably Apple is keeping the continuous detection for SpO2 in their future series 7 watch so that the isheeps would feel the dire need to upgrade immediately.
Well dosnt they meseure different things.
Apple watch meseure the percent and the real one meseure total amount. It means you can be very sic and apple watch still gives you the 👍🏼.
Hey man i do weightlifting and powerlifting, could you recommend me a watch for that im also in a budget so don't go expensive pls
Apple Watch SE is the best bang for the buck
Depends what you need out of it. Some good and cheap fitness bands out there, like mi band. All the apple watches are good, just look at the features and price and decide what fits your needs.
Just try NOT to move your hands during this 15 seconds. First clip the blood oxygen meter on one of your fingers of your right hand, and then tap “start” on Apple Watch with your middle finger of your right hand. Even the Apple Watch says that try not to move during the measurement. Otherwise Great video, thanks for sharing ! 👍🏽
I use the Montblanc Summit 2 as my Smartwatch, the Heart Hate from measures I get from it compared to the same small you have or to the big one you put on your wrist against your chest, ALWAYS matched, where when I compared with Apple Watch (Series 5, didn't try the 6 yet) I always got 10~15 less. I trust 100% from what I see on my Montblanc Summit 2, but not from what I see on Apple watch
I Just got the watch. o2 sensor is useless. It shows random number, usually 94-96% when real number (real sensor) shows 100%
This is late to this video but if other people are looking up accuracy. I am recovering from acute respiratory failure and did my own test. I was 74 on my pulse oximeter and my Apple Watch claimed I was 91. If I had this originally I would almost without a doubt be dead as I would have seen 91 and said I’m fine and went back to laying down allowing my lungs to further fill with crap. Everyone on UA-cam is healthy and not showing accuracy as I have not seen a single review of someone with low oxygen.
👍👍✌️
The small sensor is giving you constant because no hair to interfere.
That tiny sensor you have isn’t that great either.
A $40 sensor is not FDA approved. Another test you could do is buy 2 more of the $40 sensors, same brand and compare all 3. I would say 99% chance you will get different readings from all 3. How do I know this? Because I have to use these in a real life situation and to get an accurate oximeter FDA approved at the very least $200 and the best are $1000-$1200.
You were wearing your watch too high on your arm.
my watch is not accurate. it keeps reading in the 80s and my medical grade one reads just fine.
I was shocked that the Apple Watch gave a 100% reading... as soon as blood leaves the heart the oxygen levels drop off to feed the heart and lungs... it isn't possible to have 100%...
My Apple Watch has readings that are all over the place. Very unreliable and disappointing. If you want an accurate measurement, use a dedicated pulse oximeter.
That’s too bad. Maybe try adjusting your strap? Or maybe you got a faulty watch.
Mine has been almost exactly consistent with my pulse odometer, all results have been within one percentage point.
Watched and wondered...
No offense to meant, but he’s white. The current tech for this is still not hitting darling skin properly in some/many cases (friend is working on an algorithm to fix this). I would expect the deviation in some darker skin tones to be 2-3% on the low side, and up to 4% on the high side from the medical grade sensor. Personally, I’ll measure closer to this guy in the video (cause I more yellow than caramel in the arm). Friend who is darker, I’d expect a bit of difference.
Now, I’m also (without evidence) assuming that Apple isn’t making adjustments based on markers which might indicate differences in skin tone. The medical grade sensor shouldn’t have such a bias, but... well, I’m chatting without evidence. I liked this comparison a ton, and am hoping to see others do the same testing both with different skin tones, ages, and genders.
Still, great to see this. Glad a friend shared the video, because it’s a convo we are having about quan/quant info in wellness. Glad that video this is informative, to what actually happens in the tech, not just with what is (easily) marketed. Nice job, and thanks for posting this.
Thanks for commenting and checking out the video!
It’s a fair question.
I got my series 6 watch today, and have tested it against my own pulse oximeter several times, and have gotten results either exactly the same, or within one percentage point.
To your question: I’m a Black woman, with medium brown skin. 👍🏾
Do people not realize the blood oxygen is just a gimmick for the consumer to upgrade a watch that they don’t need? Aka you and me and millions others 😂😅
AK Chicago I want it to measure for athletic activities just like other sports activities show.
AK Chicago it’s not a gimmick for me. I only upgraded because of it. I have a chronic lung disease, and use my pulse oximeter regularly. Once I finish testing my series 6 against it (so far, so good!), I’m hoping my doctor and I will be able to use that data, rather than my handwritten logs.
I have an extremely short stamina and I’d think I’ll use it after my exercises.
I just get the newest watch upgrading after 4 years. I don’t mind the one extra gimmick feature.
Just get a standard watch with a sensor, people will buy a heart valve if Apple sold one lol
Oximeter.
Apple watch SE (Smart Edition, for not buying 6 edition).
It's the always on display for me. ;-)
It’s because you keep moving
Dont make a fist and keep still
Technology need to upgrade more, we can't trust on report of smart watch.
Get a Medical Grade spo2 sensor glue a watch on top of it and place straps. TADA!
You moved your arm the first two attempts.
imagine the earth were a sphere and rotating, that whole thing would never work!
i tested mine and apple five 2% above what medical grated meter show..
I don’t trust the iWarch. It mostly gives me readings in the high 80’s, and on very rare occasions, in the low 90’s., while I get simultaneous readings of in the high 90’s when I wear my fingertip oximeters simultaneously.
Now good iWatch !!! Such an expensive instrument to be this inaccurate.
Mayzjorments
Silly blood oxygen tests done on different arms.... please redo the tests on the same arm and let us know.
Stop moving your damn arms lol
I see marques Brownlee on youtube homepage I didn’t click on it because no honestly review from him.
I see One video from Techy Agent i hit the click button and smash the like button before i begining to watch the complete video. Why because you are real and not fake gentle men.
For long time I was waiting to buy a smartwatch only the first generations watches i was not impressed with.
I was really hoping that the series 6 gave more better features so that i can be real standalone device.
Apple series 6:
No mini or micro LED screen,
No camera for video call
No bigger battery
No 100 Atm waterproofing for deeper diving like the garmin fenix lineup.
No one week or at least 3 day battery life
I do not understand the design engineering and marketing team by apple I’m thinking they are lost the real balls like steve jobs snd the other important guy. Since some people leaving apple, apple is worthless now, with as results weak launches of products with every year one upgrade.
Please give me a real good advise should i buy the watch series 6 or i must wait for something else in the market.
Greetings from the Netherlands
Thank you for your kind words!
You asked if I would advise you to buy the Apple Watch series 6. It really depends on what features are important to you. For example, if you care about long battery life, super accurate GPS, great water resistance, and tough build quality... in that case I would recommend a Garmin watch. On the other hand, if you want a premium smart watch experience, a very accurate on-the-wrist heart rate sensor, and an all-around good fitness tracking experience...the Apple Watch will do. However I don’t even think you need to go with a series 6. The series 4 is still, in my opinion, a great option for most people. Or you could also go for the Apple Watch SE and save some money.
Sending my watch 6 back,, I fell hard on a wood floor n the watch did nothing,,n all fall detection is ON,,,,, NO TRUST EVER AGAIN,,, ADIOS Worthless WATCH
man, that was very awful! Apples SPO2 sensor or software are way way behind Garmins....
This looks like another Apple gimmick feature, just like the ECG feature which is inaccurate at detecting AF arrhythmia. 💁♂️
Don’t think so. I had AF (initial detect was on my iPhone) which consistently diagnosed as such. Confirmed on a multi-diode ECG. Several months later I had the medical procedure (cardio version) that put my heart back into sinus rhythm, which the iPhone then consistently recorded as such.
Andrew Speed didn’t think so. Only
AliveCor Brings World's Only Six-lead, FDA-cleared Personal ECG.
MrDominic152 That’s just straight up untrue. The Apple Watch ECG feature is FDA approved. AliveCor stopped selling their bands after the feature dropped.
Just as bad as Huawei; but 10 times more expensive
Not correct at all
Apple watch is highly accurate and iam a doctor and comparing it with oxymeter
94% is extremely low! Check your health
he literally said he held his breath...
@@juliet4093 anyways. 99-100% is healthy. Even with breath hold 95 is low. BUT AW6 o2 sensor is useless. Just bought the watch. Sensor is not accurate at all. Shows 95%, 92% when it is supposed to show 99%
